Open the charging case. The charging case status light glows according to the baery level (see page 43). NOTE: For more detailed baery level information, use the Bose app. The case baery level is displayed on the product control screen.BATTERY

Earbuds Up to 2 hours

Charging case Up to 3 hours NOTES:

• When the earbud baery level is low, a 20-minute charge with the case closed powers the earbuds for up to 2 hours.

• A full charge powers the earbuds for up to 6 hours with Immersive Audio set to O (up to 4 hours with Immersive Audio set to On).

• When the case is fully charged, you can fully charge the earbuds up to 3 times.

• When the earbuds are inside of the case, the case charging time varies. 1 Testing conducted by Bose in January 2025 using production-representative Bose QuietComfort Ultra Earbuds (2

Gen) charging case. Quick charge testing consisted of inserting earbuds with baery depleted (to the point of no audio playback) into a fully charged case and charging earbuds for 20 minutes, then resuming Bluetooth A2DP audio playback with volume set to loudness of 75dBSPL, 3-band EQ set to zero, in Quiet Mode (full noise cancellation) with Immersive Audio switched o, resulting in up to 2 hours playback time before baery depletion. Time to achieve fully charged earbuds was determined by inserting earbuds with baery depleted (to the point of no audio playback) into a fully charged case and charging earbuds to 100% baery charge. Baery life varies based on seings and usage. 2 See 1. 3 Testing conducted by Bose in January 2025 using production-representative Bose QuietComfort Ultra Earbuds (2

Gen) and IEC 60268-1 pink noise using A2DP Bluetooth audio. Volume set to playback loudness of 75dBSPL, 3-band EQ set to zero, in Quiet Mode (full noise cancellation). With Immersive Audio o, playback time was up to 6 hours before baery depletion. With Immersive Audio on, playback time was up to 4 hours before baery depletion. Baery life varies based on seings and usage. 4 Testing conducted by Bose in December 2024 by inserting production-representative Bose QuietComfort Ultra Earbuds (2

Gen) with baery depleted (to the point of no audio playback) into a fully charged Bose QuietComfort Ultra Earbuds (2

Gen) charging case and charging earbuds to 100%, then resuming audio playback until baery depletion. Testing resulted in three complete charging cycles by the case before a full charge was no longer possible.42
